Karaoke Equipment & Supplies

so far i am having:
*kids activity room so they can play stuff like musical chairs – so they don’t have to be with there family all night and they can have fun
*Karaoke
*then a DJ
*foods – a bit of everything
*tables to seat everyone

allot of people will be my family because i want them there.

can u think of anything else that i can do?

also everyone will be dressed formally and in black and white and i will be in a different colour.. so i stand out.. please help with ideas.
OMG – lol the musical chairs is for the young people not me!! x
